This is a simple example Apollo Android app inspired by https://github.com/apollographql/frontpage-ios-app. It is a very basic app, but it does demonstrate how you can hook up GraphQL query results to your UI using MVVM architecture.
The code in PostsRepository.kt fetches data based on a GraphQL query defined in PostListActivity.graphql. That query refers to a fragment defined in PostListItem.graphql, which nicely illustrates how you can describe your data needs next to the UI component that uses them.
We followed the following workflow while working GraphQL endpoint and the Apollo SDK.
- Write and test queries using GraphiQL.
- Use the Apollo plugin to generate model types from the schema and queries.
- Integrate ApolloClient into the app, passing in the generated queries and write the logic for handling already-parsed responses.
